Adjusting ring for a charging device, more preferably for an exhaust gas turbocharger of a motor vehicle

Abstract

The invention relates to a charging device, more preferably an exhaust gas turbocharger for a motor vehicle with a variable turbine/compressor geometry ( 1 ) with a plurality of adjustable guide blades, which are each engaged with an adjusting ring ( 2 ) via a corresponding lever ( 3, 3 ′) and which are preferentially jointly adjustable through said adjusting ring. Through a reinforcement ( 10 ) of a plurality of engagement regions ( 7, 7 ′) of the adjusting ring ( 2 ) which are in contact with an adjusting lever ( 3, 3 ′) each, higher force transmission from the adjusting ring ( 2 ) to the adjusting levers ( 3, 3 ′) is made possible without disadvantageous plastic deformation of the adjusting ring ( 2 ) or of the adjusting levers ( 3, 3 ′).
